Obsessive-Compulsive Disorder (OCD): Understanding the Cycle, Symptoms, and Effective Treatment (ERP)
What is Obsessive-Compulsive Disorder (OCD)?
Obsessive-Compulsive Disorder is a mental disorder characterized by two core components:
- Intrusive Obsessions: Distressing, involuntary thoughts, images, or urges.
- Repetitive Compulsions: Repetitive behaviors or mental acts performed to alleviate the distress caused by the obsessions.
OCD is among the top 10 leading causes of disability worldwide, and approximately 65% of individuals with the disorder concurrently experience depression. Despite its severity, there are many common misconceptions, often leading those living with OCD to feel misunderstood. Individuals with OCD live with debilitating fear and anxiety, where compulsions can quickly take over their lives.
The OCD Cycle: Why Obsessions Persist
Most individuals with OCD recognize that their fears are distorted and out of proportion—that they likely will not come to pass. Yet, the anxiety, obsessive thoughts, and compulsions persist because OCD is a powerful, self-reinforcing cycle:
Obsessive Thought→Anxiety/Distress→Compulsion→Temporary Relief→Stronger Obsession
The greater the state of anxiety, and the more the person gives in to the compulsion or flees the trigger, the more strongly the compulsion will be felt next time. Acting on the compulsion and experiencing relief quickly hardwires it into the brain as a maladaptive coping mechanism, leading to progressive dysfunction. Individuals may reach a point where they are performing these behaviors for more than an hour, sometimes many hours, every day.
Different Forms of Obsessions and Compulsions
OCD can manifest in a wide variety of ways, characterized by specific, persistent, and unbearable fears.
Common Obsessional Themes
- Contamination/Germs: Fears surrounding contracting illness or contaminating others (common during COVID-19).
- Harm: Fears of harming oneself or others (often loved ones).
- Sexual/Identity: Fears surrounding sexual identity, orientation, or inappropriate actions.
Symmetry/Order: Fears related to things being out of place or “not just right.”
Egosyntonic vs. Egodystonic Compulsions
A crucial distinction in understanding OCD compulsions is their relationship to the individual’s moral compass:
Both responses—giving in to egosyntonic compulsions or avoiding triggers due to egodystonic compulsions—lead to the exacerbation of the condition.
The Neurobiology of OCD and Cognitive Distortions
Hyperactivity in the CSTC Loop
Research has found hyperactivity in the Cortico-Striatal-Thalamo-Cortical (CSTC) loop of the brain in individuals with OCD. This loop acts as a signal filter. In OCD, this filter is hypothesized to be stuck “on,” allowing anxiety signals and specific fears to become pathological and repetitive, consistent with the adage, “neurons that fire together wire together.” Genetic differences may account for some of the risk.
Distinguishing OCD from Addiction
It is important for individuals to understand that OCD compulsions are fundamentally different from addictive. cravings
One should not worry that an individual with egodystonic compulsions will act on them; rather, concern should focus on the mental safety of the person experiencing the compulsion.
Cognitive Distortions in OCD
A cognitive distortion is a distorted belief that arises in the presence of intense anxiety. Individuals with OCD tend to experience these intensely and frequently.
- Examples: At times, they may truly believe and feel convinced that the house is on fire, that they have contracted a serious illness, or that they are going to commit a harmful act.
- Nature: These distortions are not psychosis; they worsen and improve along with the OCD condition. An outside observer may not understand the thinking, but the individual generally knows the fear is out of proportion to the danger.
Exposure and Response Prevention (ERP): The Primary Treatment for OCD
The most important and effective treatment for OCD is Exposure and Response Prevention (ERP), a specific type of Cognitive Behavioral Therapy (CBT).
What is ERP? ERP is a gradual process where the individual exposes themselves to the fear (the trigger) without performing the compulsion (the response).
Principles for Successful Recovery Avoidance Worsens OCD:
- Avoidance Worsens OCD: Avoidance of the fear will cause the fear and the compulsion to become stronger. ERPrequires courage, willpower, and diligence, but it gets easier over time.
- Every Trigger is an Opportunity: Each trigger is an opportunity to re-educate your brain on what it should and shouldn’t fear. You are re-wiring the pathological CSTC loop.
Prognosis is Variable: OCD is a treatable disorder. Prognosis is highly dependent upon diligence in treatment. While full remission is possible, even severe cases can reach a point where the disorder no longer bothers the individual regularly.
